remove the finished spool from the machine at a spool delivery station.Each of the operations just mentioned is more fully describedhereinafter.

The rotatable carrier for the cores comprises a body |5 which is mountedupon a shaft i6 and which supports a plurality of core holders l1, whilethe second rotatable carrier for the flanges comprises a pair of disksl8 and I9 which each support a plurality of clutch elements 28 forengaging the flanges and which are each mounted upon a sleeve 2|, seeFig. 2, by means of a pair of bushings 22 and 23.

The shaft l6 for supporting the core carrier is supported at one end bya bearing 24 and at the other end by a bearing sleeve 25 both of whichare aflixed to or form part of the frame of the machine.

An interconnecting means is provided between the two rotatable carriersfor simultaneous movement thereof. Such an interconnecting means may beany suitable arrangement such as the chain drive shown and comprising asprocket 26 affixed to shaft I6, a sprocket 21 affixed to sleeve 2|, anda chain 28 which encircles said sprockets 26 and 21. In the illustratedembodiment the rotatable carrier for the flanges has twice as manyclutch elements as there are core holders on the other rotatable carrierso that the ratio of sprocket 26 to sprocket 21 is such that sprocket 26rotates twice for every revolution of sprocket 21.

The power drive for the rotatable carriers is intermittent so thatstationary intervals of the carriers are provided. The preferred form ofpower drive is a Geneva movement which has been illustrated, see Figs. 1and 3, as comprising a power driven counter shaft 29, a driving member38 on shaft 29, a driving pin 3| and a shoe 32 on said driving member30, and a star wheel 33 which is formed in the rear surface of body l5of the core carrier. The counter shaft 29 is driven by a main shaft 34in timed relation thereto by means of any suitable connection such as apair of intermeshing gears 35 and 36 which are mounted on main shaft 34and counter shaft 29, respectively. The main shaft 34 is rotated by anysuitable prime mover (not shown).

The automatic feeding and preparation of the flanges to thecorresponding rotatable carrier is now to be described with respect toFigs. 2 and 12.

During the stationary interval provided by the intermittent power drive,the flange carrier is reciprocated in an axial direction by an actuatingmeans. Disk 8, forming one flange carrier, is mounted on bushing 22which is provided with an annular groove 31. The actuating means forthis carrier comprises a block 38 movable within a slide 39, a post 48mounted on block 38, a link 4| pivoted to post 48, a stud 42 mounted onelectrode support 43, and a second link 44 pivoted The link 44 carries apin 45 which engages the groove 31 of bushing 22. The stud 42 isslidably mounted in electrode support 43 and is biased by a coil spring46 to an extended position. A similar linkage system is provided totransmit the motion from block 41, which is movable in slide 48, to thebushing 23 supporting disk I9, but is not particularly described becauseof the similarity.

An adjustable stop means for limiting the axial movement of the disks l8and I9 may comprise a bushing 49 on sleeve 2| between disks I8 and I9and a pair of set screws 58 and 5| threaded into opposite ends ofbushing 49 and adapted to abut the disks l8 and I8, respectively, in theforward positions thereof. A rod 52 is supported by bushing 49 andslidably engages disks l8 and II to permit axial but to preventrotatable relative movement therebetween.

The slides 38 and 48 for the respective blocks 38 and 41 are provided,respectively, .in frame members 53 and 54. The blocks 38 and 41 arereciprocated by mechanisms which are similar so that only one of them isdescribed. A toggle linkage, see Fig. 2, includes an arm 55 which isjournaled to a pin 56 on the block 38 or 41 and incudes a link 51 whichis pivoted to the frame member 53 or 54 and to one end of arm 55 by arod 58. A cam follower 58 is connected to rod 58 by a link 68 androtatably supports a pair of rollers 6| and 62 which engage therespective outer and inner surfaces of a cam 63. The cam 63 is mountedon a sleeve 64 which is rotated within a central frame member 65 by apower driven shaft 66. The formation and relative timing of the cam 63is indicated in column VII of the cam time chart of Fig. 11.

Upon rotation of power driven shaft 66, the blocks 38 and 41 are movedback and forth and the disks l8 and I8 are reciprocated on sleeve 2| toforward and retracted positions. The stud 42 and the coil spring 46 forma resilient connection for one end of link 44 so that any additionalmovement of blocks 38 and 41 after disks l8 and I9 abut set screws 58and 5| is taken up by said resilient connection.

The flange blanks are supplied in the form of flat circular disks 61each provided with a central hole 68, see Fig. '7. Said flange blanks 61are stacked within vertical flange feed tubes 65, see Fig. 3, and arefed one at a time from the bottom of these stacks by any suitablemechanisms, only one of which is shown. Such a feeding mechanism maycomprise a slide 18 which is moved back and forth within a slideway 1|by means of a reciprocating connectingrod 12 in turn driven by a cammeans designed to correspond to column VI of Fig. 11. The slide 18pushes the individual flange blanks into the top of the flange chute 13which is preferably composed of non-magnetic material and which conductsthe flange blanks to the flange feeding station, see Figs. 5 and 6.

The purpose of the flange feeding station is to effect the location ofthe flange blanks in the flange carrier or disks i8 and I9 during thestationary interval of the intermittent power drive for said carrier andwhile said disks l8 and I9 are in forward position.

The flange feeding means is primarily composed of a plunger axiallymovable to carry a flange blank into engagement with a clutch element ofthe rotatable carrier. In the particular adaptation of the presentinvention a pair of plungers 14 and are used and are mounted for axialsliding movement in respective supports 16 and 11. A rod 18 is attachedto plunger 14 by means of a connector 19 and is also axially slidablewithin the supports 16 and 11.

The reciprocation of plungers 14 and 15 is accomplished by an actuatingmeans which is timed to move said plungers to forward positions duringthe forward positions of disks l8 and I9. Such an actuating means maycomprise a crank member 88 which is rotatably mounted in a sleeve 8| ona standard 82, is pivotally connected to the adjacent ends of plunger 15and rod 18, and has a crank arm 88 for rotatably supporting a camfollower 84. Said actuating means also includes a cam member 95, seeFig. 2, which is adapted to impart a rocking motion to the crank member99 so that rotation in one direction moves plungers 14 and 15 towardeach other while rotation in the other direction moves said plungersaway from each other. The contour and timing of cam member is indicatedin column V of the time chart of Fig. II and is seen to be very similarand timed with respect to cam 99, see column VII, for moving the'disksI9 and I9 to forward position so that the plungers 14 and 15 are inforward position when disks I9 and I9 are also in forward position.

The flange supply means includes the flange chutes 13 into which theflange blanks are fed by the slides 19 and also includes holders 95which are attached to supports 15 and 11. The holders 99 are providedwith semi-cylindrical grooves in which the plungers 14 and 15reciprocate and also have collars 81, see Fig. 6. A stripper means forthe flange feeding plungers preferably comprises a pair of pawls 99which are pivotally mounted on each holder 99 by bolts 99 and which arebiased to abut collar 91 by means of a coil spring 99. The free ends ofpawls 98 are inclined and are spaced so that a flange blank may be movedthrough them by one of the plungers 14 or 15 but will be stripped fromthe plunger during its return movement.

A guard means is located in axial alignment with plungers 14 and 15 tosupervise the location of the flange blanks in the disk carriers I9 andI9, and, by way of example, is illustrated as including a bracket 9Iattached at one end to the machine and supporting at the other end across rod 92. The cross rod 92 supports a pair of sleeves 93 on eachend, is provided with a pair of slots 94 for cooperating with pins 95 oneach of sleeves 93 to limit the axial movement thereof, and is encircledby a pair of coil springs 99 which hold sleeves 93 in extended positionwith pins 95 against the opposite ends of slots 94. The rod 19 alsoslides in the bracket 9I.

The clutch elements 29 which are provided for the flange carrier are nowto be particularly described with respect to Fig. '7. A ring 91 isprovided with a peripheral groove 98. A plurality of engaging means arespaced around the ring and may include pins 99 each of which has at oneend a pair of teeth I99 and IN and each of which are provided at theother end with a groove I92. A circular coil spring I99 is locatedwithin pheripheral groove 99 and urges the'engaging means toward thecenter of the ring 91 but a shoulder I94 is provided on each pin 99 tolimit the radial movement under the action of spring I93. The teeth I99and IN on the engaging means each have one side sloping in the samedirection, the slope on tooth I9I being steeper than on tooth I99. Thepins 99 are located in said ring 91 with the inclined sides of the teethI99 and MI facing to engage the flange blank as it is fed thereto by theplungers, in the example shown by plunger 14. The teeth I99 and IM alsohave perpendicular surfaces which are opposite the inclined surfaces andwhich will act as strippers if the flange blank for any reason tends tostick to plunger 14.

The ring 91 is threaded for attachment to the disks I9 or I9 and isprovided with holes I95 for facilitating removal of said clutchelements. Locating pins I99 are inserted into the end of the plungers 14and 15.

The flange blanks 91 are inserted into the flange carrier in thefollowing manner. The slides 19 feed the flanges 91 from the bottom 09the stacks in flange feed tubes 99 into the flange chutes 13. Theflanges 91 are conducted in pairs Into a position best shown in Fig. 8and in j which they rest upon holders 99 and in which they aremaintained in upright position by 001-- lars 91 and pawls 99. Uponactuation of the crank member 99 by the cam member 95, the plungers 14and 15 are moved toward each other, the locating pins I99 on theplungers 14 and 15 enter the central hole. 99 in the flange 91, thepawls 99 are cammed outwardly against the action of coil springs 99, andthe flanges 91 are carried by plungers 14 and 15 into engagement withthe engaging means of the clutch elements 29 on the disks l9 and I9. Inthe meantime the disks I9 and I9 have been moved toward each other toabut the adjustable stop means and to move clutch elements 29 intocooperative relationship with the guard means. The plungers 14 and 15move theflanges 91 into abutment with the sleeves 99 of the guard meansand into engagement with the inclined surfaces of the engaging means ofthe clutch elementcausing movement of pins 99 against the action ofspring I93. In proper location of the flange 91. the engaging means ofthe clutch means prevents easy or accidental removal of the flange 91therefrom. The plungers 14 and 15 are thenreturned to restractedpositions under the supervision of cam member 95 and if for any reason,a flange should stick to the locating pin I99 or either of the plungers14 and 15, the pawls 99 under the action of coil spring 99 would knockthe flanges from the plunger so that no damage could result to themachine by such abnormal condition.

The entire loading cycle as just described takes place during thestationary interval of themtermittent power drive for the flangecarrier. During the succeeding cycles the flange carriers areintermittently rotated to bring the flanges into one or more preparatorystations at which.

the flanges may be stamped, deformed and slotted before movement to theassembly station.

A pair of punch presses for preparation of the flanges are operated bythe actuating means for the flange carriers. One or more sets of diesare operated by said punch presses and such dies may be provided andarranged in various combinations. As shown in Fig. 2, an anvil I91 isprovided with a pair of stationary dies I99 and a pair of movable dieblocks I99 are provided with dies II9 which are complementary tostationary dies I99. The set of dies I99 and H9 may be of standardconstruction and their design to perform the various operations, namely,slotting, embossing and deforming, requires only the skill of a toolmaker. The movable die blocks I99 are adapted to reciprocate with theblocks 99 and 41 but are relatively movable with respect thereto bymeans of adjustable connections I I I each of which includes a wedge II2operated by a bolt I I3 threaded in block I99 and swiveling in wedgeII2. Prior to each punching or forming operation, the disks I9 and I9are moved axially by reciprocation of blocks 99 and 41 so that theflanges which have been loaded into the clutch element 29 of said disksare moved adjacent the stationary dies I98 on the anvil I91. At the sametime the movable die blocks I99 are moved toward the disks and dies I I9enter the openings in clutch elements 29.

The forward positions of .disks I9 and ll are .eration, the slottingcontrolled by the adjustment of set screws til and II so that theflanges B1 in disks II and I9 are in proper relation to the stationarydies III! while the extreme positions 01 dies I I are controlled byregulation of the adjustable connections III so that the dies I08 and II0 may cooperate properly to perform the particular punching operationon the flanges '1.

A passage III is provided in anvil I07 and is adapted to conduct theflange cut-outs away from the dies. A negative pressure may bepreferably created within passage I01 to facilitate its operation as aconduit for flange cuttings to waste.

While the dies I08 and Hi can be designed to perform the slotting,embossing and dishing oi the flanges in a single operation, it ispreferable to accomplish the flange preparationinmore than one step. InFig. 12, the preferred form of location and design of the dies forforming the flanges are shown. In this form of punch press a pair oimovable dies H4 and H5 are appropriately mounted and located on eachmovable die block Ill so that upon axial movement of the disks IE andIII the dies Ill and II! enter the openings in two of the clutchelements 20. The flange blanks 61 have been omitted in Fig. 12 from theclutch elements opposite the dies H4 and H5 for better illustration ofthe forming elements of said dies. The movable die H4 has a locating pinH6, 9. pair of slotting fins Ill, and embossed characters H8. Themovable die II5 also has a locating pin H9 and has a convex end with aplurality of pimples I in quadrature thereon so that the flange isdished and provided with a plurality of dimples by the action of thisdie. Complementary stationary dies, similar to sta tionary die I 08 areprovided on the anvil ill? tor cooperation with the movable dies I I4and I 55 just described.

The preferred steps of flange preparation are now to be described. Theflange blank El has been located in the clutch elements on the flangecarrier as Previously described and during the same cycle is rotated adistance equal to the spacing of clutch elements 20. Dining the stationary interval of th next cycle of machine op s II? and embossed characters III accomplish slotting and stamping of the flange blankwhereupon the slotted and em= bossed flange 6] is moved to a positionopposite movable die H5. The convex endand pimples I20 thereon ofmovable die I I5 complete the prep= aration of flange 61' by dishingand. providing projections in the same. The form of the flanges justprior to the welding operation is also shown in Jones Patent No.1,754,205 and in our copending applications for a Method of weldingspools, Serial No. 683,154, and for an Electric welding Ina-=- chine forall-=metal spools, Serial No. 683,155 both filed on even date herewith.The advantages and purposes for certain of the iormings on the flangesare also set forth in said patent and applications. The formed flangesremain in the flange carriers and are rotated at intervals until theyarrive at the assembly station in alignment with the cores in the coreholders I1 of the other rotatable carrier.

The feeding and movement of the spool cores to the assembly station isdescribed in the foilowing. The core holders I! on the body I5 are eachcomposed of a pair of jaws, a stationary jaw HI and a movable jaw I22which is mounted on a plate I23 pivotedto stationary jaw IZI by meam ofa bolt I24. The jaws IZI and I22 in the case 01 each core holder I! arebiased to aooas'rt closed position by a coil spring I25 which isconnected between said plate I23 and the body II- The jaws Ill and I22are provided with semicylindrical grooves which form a cylindricalreceptacle for the spool cores when the jaws are in closed position. Apair of pins I26, see Fig. 15, are mounted in the groove of either Jaw,preferably the movable jaw I22, and co-operate with slots in the spoolcore in a manner to be explained hereinafter.

The delivery of the spool cores to the core holders I1 of the rotatablecore carrier is accomplished by a core feed hopper and a transfer meansfor moving the cores individually from said hopper to a position betweenjaws HI and I22.

The core feed hopper, see Fig. 13, includes a trough I21 which has awidth corresponding to the length of the cores and includes a verticalguideway I28 in which the cores I28 are stacked one above the other.Movement of the cores from the trough I21 to the guideway I28 isfacilitated by reciprocating a plate I30 which is in the bottom oftrough I2'I. Said plate I30 is supported at one end upon a roller I3Iand at the other end by a bracket I32 which is journaled upon a cam I33eccentric to a rotating shaft I34. The trough I2? and the verticalguideway I28 are supported by a central web I35 which is connected to anarbor I36 that is attached to a lug I3l, see Fig. 4, on the frame of themachine. The shaft I is rotatably mounted along the side of the machineand is rotated from the main shaft 3% through a gear train whichincludes the pinion gears I38 and I39.

The tubes iii! are supported in guideway I28 by a plate I40, see Fig.13, which is fastened to central web I35 by a bolt I. A pawl I42 ispivoted to plate Mil by a pin I43 and has a counterweight I44 and a lugI45. A spring pressed pin I46 is slidable within plate I and abuts thelug 645 so that pawl I42 is normally held in position to prevent tubesI29 from falling out of guideway I28. A cam surface I47 on pawl I42 isnormally held against the lowermost tube in guideway E28 by thecounterweight I44 and pin I46 to prevent the weight of the superjacenttubes from moving said lowermost tube out of the guideway.

The transfer means includes a shaft I48 and a pair of sectors I49 andI5!) mounted in spaced relation onsaid shaft I48. The sectors I 49 andi559 may be clamped to shaft I48 as by means of a set screw I5I, seeFig. 13. The sectors I49 and 558 are axially spaced on shaft I48 at adistance slightly greater than the length of a core I 29. Core grippersare provided on each of sectors I49 and I59, are adapted to resilientlyengage the ends of a core I29, and may be composed of pins I52 which areslidably mounted in said sectors and normally maintained in extendedposition by a spring I53, see Fig. l.

The shaft I48 is supported along the side of the machine by a pair ofbearings I54 on the machine and at one end by a yoke I55, the other endof shaft 888 has a pinion I56. The shaft I68 is rotated in timedrelation to the power drive, first a fraction of a revolution in acounterclockwise direction, see Fig. 13, for movement of a core I 29from vertical guideway I28 to a position between jaws I2I and I22 andthen in a clockwise direction to its original position so that gripperpins I52 engage the ends of the lowermost core I29 in said guideway I28.The means tor rotating the sectors I49 and I of the transfer meanscomprises a counter shaft I51 rotatably supported in bearings I59, apinion I59 on shaft I51 and in mesh with pinion I56, a rack I60 slidablein a guide.I6I on frame 162 and in mesh with a pinion I63 oncounter-shaft I51, and a cam member I64, see Fig. 14, for reciprocatingrack I60 and mounted upon the main shaft 34. The rack I60 is movablysupported from a bracket I65 on the back of frame I62 and by a link I66pivoted at one end to said bracket I65 and at the other end to one endof the rack I69 by a pintle I61. A cam follower in the form of a rollerI69 is mounted on the end of pintle I61 and moves in a cam slot I64 ofsaid cam member I64. The complete contour and the relative timing of thecam I64 is shown by column VIII on the time chart of Fig. 11.

The jaws I2I and I22 of the core holders I1 are operated at the corefeed station during the stationary interval of the rotatable carrier forthe cores and in timed relation to the transfer means. For this purposeeach core holder has a roller I69 on the plate I23 which also carriesthe movable jaw I22. An' actuator controls the movement of said movablejaw I22 and includes, see Fig. 1,-

an arm I19 which is adapted to engage the roller I69 of the core holderat the core feed station, a shaft I1I rotatably mounted on said machineand connected at one end to said arm I10 and at the other end to asegment I12, a cam member I13 on the main shaft 34 of the machine, and alink' I14 which may be intermediately provided with a turnbuckle I15,which is pivotally connected at one end to segment I12 by a pintle I16,and which supports at its other end a cam follower I11 adapted to engagethe periphery of cam member I13. A coil spring I19 is fastened tosegment I12 and normally maintains cam follower I11 against theperiphery of cam I13 which has a contour and is relatively timed to theother mechanisms according to the chart in column IX of Fig. 11.

The spool core I29 is preferably formed in the manner disclosed in thepatent to Chamberlin No. 1,649,539 and is accordingly provided with aslot I13 at the seam of the core, see Fig. 15, and with a slot I90 whichis diametrically opposite slot I19 and which is wider and shorter thansaid slot I19. The cores pass through the core feed hopper and are movedby the transfer means to a position between the jaws I2I and I22 withoutregard for the location of the slots I19 or I90 with respect to theremainder of the machine.

The existence of a predetermined relationship in the finished spoolbetween the slots in the flanges and the slots in the core is necessaryin view of the subsequent spooling of photographic film onto the spools.The provision in the flanges of slots which are in definite relation tothe carrier for the flanges has already been described. The location ofthe core with the slots therein in deflnite relation to the rotatablecore carrier is to be next explained.

The core I 29 is positioned between the jaws I2I and I22 by the transfermeans. The jaws I2I and I22 are biased to closed position but the pinsI26 in the semi-cylindrical groove of the movable jaw I22 prevent thejaws from assuming the closed position unless the core is in properposition with the pins I26 extending either into slot I19 or slot I90.In the illustrated embodiment of the invention, see Fig. 15, the pinsI26 are spaced apart a distance which is greater than the length of slotI90 but less than the length of slot I19.

.. Rotation of the core within the jaws will move the core I29 until thepins I26 enter the slot I19 but at the same time the pins I26 can notenter slot I90 because of the particular spacing of said pins I26. Suchrotation of the core is accomplished by means of a spinner which isaxially movable to engage and rotate the core and which is provided witha stripper for disengaging said core and spinner upon retraction of thespinner.

The spinner comprises a head I9I which has a knurled pin I92 adjustablyattached thereto by a pair of lock nuts I93, see Fig. 15. The head I9Iis mounted on the end of a shaft I94 which is rotatably supported alongthe side of the machine in the frame I62 by a bearing I95 thereon andwhich is mounted for axial movement. The shaft I94 is continuouslyrotated by means of pinion gear I39 which is driven, as beforementioned, through a suitable gear train by the main shaft 34 and whichmeshes with an elongated pinion I96 on shaft I94. A collar I91 is pinnedto shaft I94 and is provided with a peripheral groove I99. A yoke memberI99 is intermediately pivoted to the frame I62 by a pin I90, supports atone end a pair of rollers I9I which engage the groove I99 of collar I91,and supports at theother end a cam follower I92 which engages a slot I93in the periphery of a cam I94 on the main'shaft 34. The contour of camI94 and the timing of the axial movement imparted to shaft I94 isindicated in column X of Fig. 11. Since the end thrust of the spinnermay cause axial movement of the cores I29 between jaws I2I and I22, thesector I49 is formed to be adjacent the end of core I29 during itsengagement with the spinner. The

cam I64 for rotating the shaft I49 returns sector.

I49 to the position shown in Figs. 13 and 15 to abut the end of core I29before the cam I94 has axially moved shaft I94 to bring knurled pin I92into engagement with the core I29 between the jaws I2I and I22. Thisrelative timing of cams I64 and I94 is also indicated by comparison ofthe time charts for these cams in columns VIII and X, respectively, ofFig. 11.

A stripper is provided on the end of the spinner and functions toextract the knurled pin I92 of the spinner from the engagement with theinside ofcore I29 after proper location thereof between the jaws of coreholder I1. Such a stripper may comprise a cap I95 which is slidablymounted on head I9I and which is movable in extreme positions to coveror expose the knurled pin I92 of the spinner. A coil spring I96encircles head I9I and normally maintains cap I95 in position to coverpin I92. Upon axial movement of the spinner toward the core. cap I95abuts the end of core I29, see Fig. 15, and further axial movement ofthe spinner by cam I94 thrusts the pin I92 through cap I95 intoengagement with the interior of core I29.

The Geneva movement, the cam I64 of the transfer means and the cam I13of the actuator for the jaws I2I and I22, are in timed relation so thatduring the first part of the stationary interval the jaws I2I and I22are maintained in open position by the actuator, compare columns 11,VIII and IX. With the jaws I2I and I22 in open position, the cam I64turns the transfer means to carry a core to a position between the jawsand before return of the transfer means, the actuator for the jawspermits the jaws I2I and I22 to close or only partially to close if pinsI26 do not happen to enter slot I19. The transfer means returns tooriginal position. The spinner is moved into engagement to rotate thecore and is then retracted. All of these movements take place during thestationary interval provided by the Geneva movement for the corecarrier. Hence a core I29 is fed and located in a core holder I I at thecore feed station during each cycle of the machine. The actuator permitsthe jaws I2I and I22 to remain biased to closed position until after thecore holder has been moved from the core feed station and away from theinfluence of the actuator.

The rotatable carrier for the cores is turned by the Geneva movement sothat the core holders I'I arelocated at the core feed station, theassembly station, and a spool delivery station during the stationaryinterval of the intermittent power drive. The steps of feeding the coresat the core feed station and of locating the cores with their slots inproper relation to-the carrier have just been described. The core holderill with the properly positioned core is then rotated until the coreholder arrives at the assembly station. The rotatable carrier for theflanges at the same time carries a pair of flanges with slots ofindexing the carriers, the stationary jaws Hi 01 the core holders H areprovided each with an auxiliary jaw I97 which is provided with a notch$198. The discs 88 and i9, forming the flange carrier, are providedwithperipheral notches W9.

A shaft 200 is supported by the machine and in turn supports a bellcrank 20! and a second bell crank 202. The bell crank 20I has at the endof one arm a tooth 203 which is adapted to engage the peripheral notchesI99 oi the flange carrier. A coil spring 204 is connected between theother end of bell crank 2M and an anchor 205 on the machine. A tooth 206is located on one end of bell crank 292 and is adapted to engage thenotch I98 of the auxiliary jaw I91. An arm 20? is mounted upon a shaft208 on the machine and rotatably supports a cam follower 2% whichengages the periphery of a cam 2 I mounted on the main shaft 34. Asecond arm 259 is also mounted upon shaft 208. A link 2I2 is pivotallyconnected between the arm 2 and the other end of bell crank 2612 and iscompressible against the action of a coil spring H3. The bell crank 202has a lug 2M which is adapted to be engaged by an adjustable pin 2 I 5which is mounted in a bushing 2I6 on bell crank 2M.

The contour of earn 2! is illustrated in Fig. l and in column III ofFig. 11, while the relative timing of this cam 2! with respect to theother cams of the machine is indicated in Fig. 11. Immediately after thearrival of a core holder ll at the assembly station for a stationaryinterval, the cam 2N3 moves cam follower 209 so that the link H2 ismoved to bring the teeth 203 and 206 on respective bell cranks 209 and202 into engagement withthe notches I99 and I98, respectively. If thereis any over-travel due to the dwell in the cam 2I0 or if either of theteeth 203 or 206 do not properly engage in their respective notches I99and 898, the coil spring 2il-l is compressed to compensate for thisabnormal condition.

Upon proper location of the teeth 203 and 206 in their respectivenotches, the flange carrie s We and I9 and a core holder I! areaccurately positloned at the assembly station with the flanges 81 and acore I29 in substantially perfect alignment. An adjusting arrangementfor the indexing means may comprise an eccentric sleeve 200' which maybe inserted between shaft 200 and bell cranks MI and 202 so thatengagement of teeth 203 and 205 with respective notches I99 and I98 maybe regulated by relative rotation of sleeve 200.

During the stationary interval with the flanges and the core properlyaligned at the assembly station, the welding electrodes are operated tomove the flanges into abutment with the ends of the core and to effectthe welding of the flanges to the core. This operation oi. theelectrodes is also disclosed in our aforementioned co-pendingapplication for an Electric welding machine for all-metal spools, butwill be briefly described at this time. As shown in Fig. 2, an electrode2I'I is slidably mounted in the electrode support 43 and a bushing M8 onthe top of standard 32. A jaw 2H9 is intermediately positioned onelectrode 2! l. A second electrode 220 is slidably supported in theopposite electrode support 43 and bushing 2 l 8 on a standard 82. A rod22! extends through sleeve 2i and is connected at one end by a connector222 to electrode 220 and supports at the other end a jaw 223. A rockeram 224 is rotatably mounted on a shaft 225 and is pivotally connected ateach end to the jaws 2I9 and 223. A cam 226 has a contour correspondingto the time chart of column IV in Fig. 11 and rocks the rocker arm 224through a connection, not shown in this application but fully describedin our copending application just mentioned. 7

Rotation of the rocker arm 224 in a clockwise direction as viewed fromFig. 2, causes electrodes 2H and 220 to move towardeach other. Upon suchmovement, the electrodes pick up the flanges which are held in theclutch members of discs i8 and i9 and carry them to positions adjacentthe ends of the core in coreholder H. A conductor bushing 221 isattached to electrode 2" and a second conductor bushing 228 is attachedto electrode 220. A welding current is supplied through bushings 221 and228 to the electrodes 2!? and 220 in the manner disclosed in ourcopending application. After the welding operation has been performed,the cam 226 retracts the electrodes 2i! and 220 and permits furtherrotation of the flange carriers I2 and I 9.

Since the core in the core holder at the assembly station is subjectedto various strains and stresses, especially during the weldingoperation, it has been found advisable to provide auxiliary clampingmeans for squeezing the jaws I2I and H22 together. Such a clamping meansmay be composed of a stationary cam 229 and a linkage which is connectedto the movable jaw I22. Specifically, the linkage comprises an arm 230which is pivoted to the body I 5 by a pin 23I a link 2232 which ispivotally connected at one end to the plate H23 of the core holder I?and at the other end to the free end of arm 230 by a rod 233, and aroller 234 which is mounted upon rod 233 and which is adapted to engagethe periphery of stationary cam 229. A coil spring 235 encircles link232 normally to hold the roller 23! in contact with the periphery of cam229. Consequently, as the core holder I! is rotated from the core feedstation, the roller 234 rides up on the rise of cam 229 and compressesspring 235 and jaws HI and 922 are squeezed tightly together.

For proper cooling of the welded spool, the

pressure created by the stationary cam 229 is maintained for some timeafter the core holder leaves the assembly station, but is relieved priorto the arrival of the core holder at a spool delivery station which willbe described next.

The spool delivery station is illustrated in Figs. 8, 9 and l0. The coreholders I1 are rotated from the assembly station to the spool deliverystation by the Geneva movement which'also provides a stationary intervalfor the core holder at the delivery station. The path of the carrier isindicated by the dotted arc of Fig. 9, while the path of the corecarried by the core holder is indicated by the dot-dash arc of Fig. 9.

The spool delivery mechanism is mounted along side of the machine upon aframe 236. A shaft 231 is supported by bearings 236,- which are mountedin frame 236. Adjacent the spool delivery station, the shaft 231supports a pair of members for engaging the finished spool in the coreholder I1. Such members 239 are slidably mounted on shaft 231, are eachprovided with arms 240 having pins 2 to enter the interior of the spoolcore and are normally drawn together by a coil spring 242.

A collar 243 is fastened to shaft 231 and supports a linkage comprisingan arm 244 pivoted to collar 243 and links 245 between the ends of arm244 and the respective members 239, A yoke member 246 includes a pair ofrods 241 which are connected to one of the members 239. A spindle 246extends through the interior of shaft 231 and is adapted to engage a pin249 came yoke member 246.

The members 239 and arms 249 of the delivery mechanism are normally heldin closed position by the coil spring 242 but upon axial movement of thespindle 246 within shaft 231, the yoke member 246 moves one of members239 to open position and the other member 239 is also moved to .openposition through the medium of arm 244 and links 245. A cam meanscontrols the axial movement of spindle 246 and includes a cam member 269which is mounted on the main shaft 34v and a rocker arm 26I which isintermediately pivoted to frame 236 by a pin 252, which carries, at oneend, a lug 263 for engaging the end of spindle 249 and which carries, atthe other end, a cam follower 264 for engaging the face of cam member266. The contour of cam member 250 is indicated in column XII of Fig.11, from which it will be noted that the pins 24I of the arms 240 on thedelivery mechanism grip and release the finished spool all during thestationary interval of the intermittent power drive for the corecarrier.

The delivery mechanism also includes an actuating means for rotating theshaft 231, first in one direction for a fraction of a revolution andthen in an opposite direction. The actuating means comprises a cam 265which is mounted on main shaft 34, a gear segment 256 which is rotatablysupported by the frame 236 and a pinion gear 261 which is pinned toshaft 231. The cam 255 is provided with a slot 256 for imparting themovement indicated in column XIII of Fig. 11 to the gear segment 256.The connection for transmitting the cam motion includes an arm 259pivoted in a bracket 260 on frame 236, see Fig. 10, and a link 26Ipivotally connected to the free end of arm 259 and to the gear segment256.

From a comparison of columns X11 and XIII of Fig. 11, it will be notedthat when the delivery mechanism is in the position shown in Fig. 9,

the arms 246 are first separated, at which time An adjustable stop meansmay be provided for accurately controlling the rotation of shaft 231,and may comprise, see Fig. 10, a winged sector 262 which is attached toshaft 231 and which supports a pair of bushings 263 for the support of apair of set screws 264. One of set screws 264 is adapted to abut a lug266 on the frame 236 for limiting the rotation of shaft 231 in onedirection while the. other set screw 264 is adapted to abut the frame236 for limiting rotation of shaft 231 in the reverse direction. Thelink 2" is compressible against the action of coil spring 266 in orderto take up any excess motion imparted by the cam 266 after set screw 264has come in contact with lug 266.

An actuator for controlling the positions of the jaws comprising thecore holder I1 operates in timed relation to the spool deliverymechanism just described. Such an actuator comprises an am 261, see Fig.1, mounted on the end of a shaft 268 which is supported by the machine.A segment 269 is fastened to the other endof shaft 266 and includes ahook 210 for engaging the other end of the coil spring I16 which isconnected to the segment I12 of the actuator previously described. Anarm 2" is pivoted to the frame and to a link 212 which includes a turnbuckle 213 and which is pivoted to the segment 269. A cam 214 is mountedon main shaft 34 and is adapted to engage a cam follower 216 which isrotatably mounted on a pivotal connection between arm 21I and link 212.The contour of cam 214 is indicated in column XI of Fig. 11 and is suchthat the jaws I2I and I22 of the core holder at the delivery station arefirst in closed position until gripped by the arms 246 and pins 2 of thedelivery mechanism and said jaws are then opened for the remainder ofthe stationary interval of the core holder and for a portion of therotating interval. The cooperation of the actuator and deliverymechanism is such that the cam 256 does not rotate the arms 240 untilafter the jaws I2I and I22 have been opened by the actuator. As beforedescribed, after the arms 240 are swung to move the finished spool fromthe core holder, then cam 250 operates the arms 240 for release of thespool.

The actuator for the jaws of the core holder at the delivery stationreturns to a position to permit the jaws of the next core holder toarrive at the delivery station in closed position during.

the next cycle. Furthermore, the jaws I 2| and I22 are biased to closedposition and move through an intermediate position, shown at the top ofFig. 1, before the core holder arrives at the core feed station.Accordingly a stationary rail 216 is attached to the machine and isadapted to engage the rollers I89 of the core holders to maintain themovable jaw I22 in open position during passage of the core holderthrough said intermediate position and during approach of the coreholder to the core feed station.

A rsum of the operation of the machirfe will now be briefly set forth.The flange blanks 61 arefed to the disks l8 and I! by the flange feedingmechanism described with reference to Figs. and 6, the flanges beingheld in disks i8 and i8 by the clutch elements 20 specifically describedwith reference to Fig. '1. During the various stationary intervals ofthe disks I 8 and IS, the flanges are embossed, slotted and deformed bydies carried on punch-presses including the movable blocks 3! and 41.The intermittent power drive and 202 now function and cooperate with anotch IS! in the flange carrier and a notch I98 on the core carrieraccurately to align the flanges and the core. At this time, theelectrodes 2 H and 22' are operated to remove the flanges from disks IIand i9 and to move said flanges into abutment with the ends of the coreheld by the core holder.

- Application of the welding current unites the flanges to the ends ofthe core. The jaws Hi and I22 are firmly clamped together by the ac tionof the stationary cam 229 and the associated linkages. After retractionof the electrodes, the intermittent power drive again rotates thecarriers and the finished spools are rotated into the spool deliverystation. The arms 240 of the delivery I mechanism grasp the ends of thespool, the actuator including arm 262 moves the supporting roller I69 toopen jaws Hi and I22, the cam. 266 causes rotation of the arms 240 tomove the spool away from the jaws of core holder i! and the cam 250causes operation of arms 240, so that the finished spool is released anddropped into any suitable receptacle.
